SEDIMENT SEPABATOB.

Application filed September 21, 1927. Serial No. 220,890.

10 suspension to be precipitated;

Another object of the invention is to providean apparatus of the nature referred to adapted to separate and retain therein sediment both of heavy and light specific gravity,

15 as well as to precipitate and maintain therein matters in suspension and prevent same from passing out withthe waste waters.

A further object of the invention is to provide a device of this nature in which the .2 oils or fatty substance that may accumulate therein may be automatically discharged to a grease trap to which this apparatus may be attached, or to any other source.

A. still further object of the .invention is 25 to provide an apparatus of this nature with means for removing any sediment that may accumulate therein. f

Other objects and novel features of construction of my invention will become ap- 30 parent as the specification proceeds.

1n the drawings forming a part of this specification 2 Figure 1 is a top plan view of an apparatus embodying my invention,

Fig. 2 is a sectional view thereof taken online 22, Fig. 1,

Fig. 4: is afragment-a1 top plan view of a modified form of the discharge end of the device, and Y I Fig. 5 is a sectional view on line 5-5, Fig. 4.

Referring now to the drawings in detail, in which like numerals refer to the same parts throughout the several views, indicates a sediment separator and retainer which may be connected by an inlet pipe 11 to a sink or drain not shown, as these elements form no part of my invention. Likewise the outlet or discharge end of my device may be connected by an outlet pipe 12 which may be connected to a grease trap not shown, or to any other receptacle. 55

The separator 10 com rises a receptacle or tank 13 having upper ront and rear wall sections 14 and 15 vertically disposed and vertically disposed upper side wall' sections 16 and 17. The front and rear walls are provided with inwardly inclined sections 19 and 20 respectively, and the side walls are provided with inwardly inclined sections 21 and 22 respectively, the inclined wall sections 19 and 20 terminating in vertically disposed lower wall sections 23 and 24 and the inclined sections 21 and 22 terminate in vertically disposed wall sections 25 and 26 and the said lower sections are joined by a bottom wall 27 to form a lower reduced area 28 in which is maintained a removable container or basket 29.

The upper front or inlet section 14 to which the inlet pipe 11 is secured, is provided with a V-shaped bafile arrangement or bufler 30 extending above and below the said inlet pipe an'd'in direct communication therewith. Parallel to 'and spaced apart from the wall section 14: is a baflie plate or wall 31 terminating. in a downwardly and forwardly inclined deflector section 32. The wall 31 and the inclined section 32 extend the entirelength of the receptacle 13. The section 32 terminates at a slight distance from the wall 14 and section 19 to form a passageway 33. Y t

The upper rear or outlet wall section 15 is provided with a horizontally disposed flanged shelf 34 extending the entire length of the receptacle 13. Spaced from'the sec- 90 tion 15 and the shelf 34 is a pipe 35 joined to and in direct communication with the" outlet or discharge pipe 12. This pipe 35 is of a larger diameter than the pipe 12 and is open at both ends thereof as at 36 and 37 95 and may extend upwardly or downwardly into the receptacle 13 as required, the object of which will presently be described. A baflie plate or wall 38 is suspended from the walls 16 and 17 at or near the center of the tank 13.

In Figs. 4 and 5 I have shown a modified form of the outlet side of the tank which consists of a horizontal shelf or flange 39 and a jll-shaped outlet buffer having an area larger than the area of the outlet pipe 12 and in direct communication therewith and extending above and below the said pipe 12.

The operation of the device is as follows: Asbefore stated, the tank 13 may be connected to a discharge pipe of a waste trap been accumulated on. top of the water may such as are used in packing houses, ab attoirs, etc., or ,to the waste discharge pipe of a restaurant sinkv As the water flows from the above mentioned sources carrying and 30 and the flow is retarded and defiected downwardly on to the deflector plate 32 where it is further retarded and any solid matter having any grease or fatty substance thereon will strike the plate 32 separating the same and permitting the grease to rise to the top, and the heavy material will fall to the bottom into the pan or basket 29. The flow or current of water will further be retarded by the ,inclined wall sections 19, 20, 21 and 22 as well as by the bafile plate 38. It is to be understood in this connection that the quieting or retarding of the flow or current of the water in the tank will greatly tend to permit of any substance that may be in suspension to finally settle to the bottom. It is also to be understood that after the tank is filled as shown in Fig. 2 and the Valve 12! on the outlet pipe 12 is opened and the water continues to enter into the tank, sufiicient water will flow out through the opening 36 and 37 in the pipe 35 and through the pipe 12, the shelf 34 acting as a bufier for any currents that may develop by reason of such outflow. It will be seen that owing to the fact that the pipe 35 is open at both endsand being larger in diameter than the pipe 12, there will be'a tendency to keep the material in the tank quiet and undisturbed. Likewise in the modified form of the outlet end of the device shown in Figs. 4 and 5, the buffer 40 and shelf 39 will have the same tendency, that is to maintain the water in the tank in as quiet a state as possible.

The layer of grease 42 which will have be manually skimmed off or a valve 43 on a pipe 44 may be opened and the grease will flow to any desired point. This grease or fatty substance may also be fed off the top by having the open ends-of the pipe 35 project upwardly, in which case the said grease may be fed to a grease trap which may be connected to the pipe 12. The accumulated heavy material may be dispensed with as desired by removing the basket 29 when the said basket is filled up. To clean the tank, a valve 46 on a pipe 47 at the bottom of the said tank may be opened permitting any dirt to flow out therethrough.

From the above it will be seen that I have provided a sediment separator and retainer efficient in operation and simple in construction and one adapted to be usedin connection with discharging waste water carrying greasy material and sediment of both heavy and light specific gravity.

While I have shown and described a preferred form of my invention, I do not limit myself to the exact showing and description, as variations may be had without departing from the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A device of the nature described, comprising a receptacle having an inlet, a V- shaped deflector at the inlet with its apex pointing inwardly of the receptacle, a wall having a downwardly inclined'defiector and separator plate opposite the inlet, a baflle plate parallel to and spaced from the wall, and removable means at the bottom of the receptacle for retaining any sediment entering through the inlet.

2. A device of the nature described, comprising a receptacle, downwardl inclined and converging sections in the 'fiont, rear and side walls thereof, a V-shaped deflector at the inlet with its apex pointing inwardly of the receptacle, a wall having a downwardly inclined deflector and separator plate opposite the inlet, a baflle plate parallel to and spaced from the wall, and remo vable means at the bottom of the receptacle for retaining any sediment entering through the inlet.

3. A device of the nature described, comprising a receptacle, downwardly inclined and converging sections in the front, rear and side walls thereof, a V-shaped deflector partly enclosing the inlet, a wall having a downwardly inclined deflector and separator plate opposite the inlet, a battle plate parallel to and spaced from the last mentioned wall, a pipe in the receptacle open at the two ends thereof, a reduced outlet pipe in communication with the first mentioned pipe, and a horizontally disposed shelf at the outlet side of the receptacle. 4 e

4. A device for separating sediment'and. fatty substance that may enter therein from a wastewater pipe, comprising a tank having downwardly inclined and converging sections in the walls thereof, a plurality of deflectors and sediment separators at the able sediment retainer at the bottom of the inlet end of the tank, a bafiie plate intertank, and means at the top of the tank for mediate the front and rear walls of the permitting any accumulation of fatty mate- 1: tank, a substantially T-shaped outlet pipe rial to be fed from the tank.
